The butterfly is very common in secondary and montane forests at low to moderate elevations (Alt. 20 - 1300m) and is often found at forest edges and grasslands. Both sexes visit flowers.
Incredibly, I have seen natural hybridisation between this species and Arnetta atkinsoni in Chiang Mai. This is the only case of mating I have ever seen between two different genera.
